CUTTING-STICK FOR PAPER-CUTTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 542,689, dated July 16, 1895.

Application led November 25, 1892. Serial No. 45 3,128. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM B. SHEFEIELD, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Cutting-Sticks for Paper-Cutting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

My invention relates to cutting-sticks for paper-cutting machines; and it consists in certain peculiarities of construction and material, as will be hereinafter set forth and subsequently claimed. l

In the drawings, FigureI is a partly-brokenaway sectional View of a paper-cutter, showing the improved cutting-stick in operating position. Fig. II is a transverse sectional view of the same, and Fig. III is a detail view of the cutting-stick.

v Referring to the drawings, the letter A indicates the frame of the cutter, which is supported on suitable legs or standards B. Grooves or slideways are formed in the frame and the knife 0r cutting-blade C slides therein and is provided with a suitable clamp D. In the horizontal table beneath the cuttingblade a groove or recess is formed, in which the cylindrical cutting-stick F is arrangd to lie. A dat barE, lying in a groove in the table, is arranged to project over and bear upon the cutting-stick and thus hold it in any position that may be desired. Bolts H, having one end secured to the bar and provided with .not become injured by striking against it.

thumb-nuts h and collars 77,', are so arrangedA that by adjusting the thumb-nuts the pressure exerted upon the cutting-stick by plate E may be varied, as will be readily under- 4o stood from the drawings. 1

The cutting-stick is preferably formed of comparatively soft metal, such as Babbitt metal, in order that the edge of the knife may The cutting-stick is further provided with a stiff-metal core G,which projects outside the frame ofthe cutter and is provided at its vprojecting end with an eye g, and by loosening the bolts H and applying a lever to the eye g the cutting-stick may readily be turned in its recess to present a fresh and nnworn 4part of its surface to the cutter.

While I have described my invention as embodied in the particular form shown in the drawings, yet it is not limited specifically to that form, nor do I Wish to be understood as restricting myself to the use of any particular metal or composition for the cutting-stick'.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination with the cutter and frame, of a substantially cylindrical cutting-stick havingV a projecting core provided with an eye, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM B. SI-IEFFIELD.
